摘要

针对具有测量不确定度、负载不确定度和电池电阻不确定度的升压DC-DC变换器，提出了一种自适应滑模控制策略。利用自适应规则对负载和电池电阻变化引起的负载和电池电阻误差进行估计。考虑到负载和传感器测量的不确定性和干扰，提出了一种自适应滑模非线性曲面，以保证系统的瞬态响应和鲁棒性。仿真结果表明，与PID方法相比，输出电压轨迹能够跟踪参考电压，输出电压响应良好。

An Adaptive Sliding Mode Control Algorithm for Boost DC-DC Converter of FCHEVs

In this paper, an adaptive sliding mode control (ASMC) strategy is developed for boost DC-DC converter with uncertainty of measurement, load and battery resistance. The error of load and battery resistance caused by the change of load and battery resistance is estimated by using the adaptive rule. Considering the uncertainty and disturbance of load and measurement of sensor, an adaptive sliding mode nonlinear surface is proposed to ensure the transient response and robustness of the system. Simulation results show that, compared with PID method, the output voltage trajectory can track the reference voltage, and the output voltage response is good.
